Decomposition of infinite-to-one factor codes and uniqueness of relative equilibrium states
Jisang Yoo
We show that an arbitrary factor map on an irreducible subshift of finite type is a composition of a finite-to-one factor code and a class degree one factor code. Using…
Multiplicity structure of preimages of invariant measures under finite-to-one factor maps
Jisang Yoo
Given a finite-to-one factor map between topological dynamical systems, we look into the pushforward map between sets of invariant…
Multiplicity of measures under factor codes and class degree joinings
Jisang Yoo
Given a finite-to-one factor code between irreducible sofic shifts and an ergodic on with full support, it is known that the fiber has at most $d…
Relative equilibrium states and class degree
Jisang Yoo
Given a factor code from a shift of finite type onto a sofic shift , an ergodic measure on , and a function on with summable variation, we prove an invari…
On continuing codes
Jisang Yoo
We investigate what happens when we try to work with continuing block codes (i.e. left or right continuing factor maps) between shift spaces that may not be shifts of finite type.…
